    Redditⓘ good to know

    “50MKII is super bright, totally the opposite of muffled. Most of the time I try to boost lower frequencies in EQ to make it sound more bottom.”

    Redditⓘ good to know

    “There’s really no difference between the plain 50mkII and the artist MKII. As long as you have tone studio the only thing you’re really paying for is the Waza speaker”

    Redditⓘ good to know

    “Generally, there is a big difference with the stock amp presets but to me, it made a noticeable improvement after I spent some time balancing the gain.”

    Redditⓘ good to know

    “The 100w can play as loud the 50. It got a power limiter from 0.5w to 100w and an headphone plug. Moreover the 50w don't have the same speaker, the 100w is more round sounding.”

    Redditⓘ good to know

    “YES. Use alternate mode though. The default sounds like crap in comparison.”
